Sentry

Error and performance monitoring for developers

Sentry helps developers fix errors and performance issues before users notice them, so engineering teams spend less time firefighting and more time building. That shift — catching failures in the normal course of shipping rather than after a customer reports them — is what separates monitoring from incident response. The company is open source on the position that everyone, everywhere should have the tools to make good software, and that making the industry accessible starts with not putting basic visibility behind a paywall.
